11820RE: [wsjtgroup] Wide Graph Display - enhancement
- Oct 8, 2013Thanks Joe and Rudy. That did it. I was way away from those settings. I
was working OK, but had the zero about +66, the Gain at 2, and the slope was
fairly high as well. It gave me a nice flat response - but also limited
what I could see of the graph. Now I have what I need.
You got me back on track.

gain = 0, slope = 0.3, N Avg 5, Bins/Pixel = 7
In cumulative, by "baseline" is about two major divisions up (20 db?) and in
current, it is one major division above the bottom.
